气候模型预测，未来几十年全球地表温度将发生巨大变化，预计全球水文循环也将随之发生重大变化。模型模拟的验证对于支持其在决策中的使用至关重要，但观测水文循环的要素具有挑战性，并且仅存在降水的独立于模型的全球数据集。我们计算全球水文循环的敏感性，在地表温度的变化，使用现有的全球降水数据集和比较的结果对来自20世纪世纪气候模型模拟的敏感性。最后讨论了这些结果对全球气候观测系统的影响。
Climate models project large changes in global surface temperature in coming decades that are expected to be accompanied by significant changes in the global hydrological cycle. Validation of model simulations is essential to support their use in decision making, but observing the elements of the hydrological cycle is challenging, and model-independent global data sets exist only for precipitation. We compute the sensitivity of the global hydrological cycle to changes in surface temperature using available global precipitation data sets and compare the results against the sensitivities derived from model simulations of 20th century climate. The implications of the results for the global climate observing system are discussed.
